Just to throw one in and with my logical head on ...
After such a weather forecast we had was it not possible to lay a plastic sheet over the pitch to capture the snow and the eventual water from the thaw??
I don't know much about grounds keeping but it just seems strange after such a strong weather warning all action at football grounds happens after the event not before!!
A frozen pitch is different I understand as unless you've got undersoil heating there isn't much to be done but waterlogged pitch resulting from a snowfall (which was forecasted days before!!).
Maybe someone in the know can put me right because as I say I know nothing about grounds keeping!!
